chlorophyll in our grass?

Question

now chlorophyll is in our grass to make it more greener right? right, so now what is in Chlorophyll to make it make the grass green?

Answer 1

The chlorophyll has evolved to absorb a particular color of light. When I say it absorbs that color, I mean that there is an electron energy state within the molecule which is elevated to the next higher energy state by absorbing a photon of that particular wave length. This increase in energy state cannot be caused by a photon of any other wavelength/color. So chlorophyll does a particularly good job of absorbing that color, which is dawn at the red end of the spectrum. Because the chlorophyl is absorbing that red color and reflecting pretty much all of the remainder of the light, the reflected light is deficient in red, causing it on average to have a green hue. All of the other colors are there in pretty close to normal proportions, but yellow balances with the purple, and blue balances with the orange, leaving the green unbalanced and thus the apparent hue of the light. Two colors of visible light balance when their frequencies are about a half octave apart.

Answer 2

chlorophyll is NOT there to make things look green!

Chlorophyll is a complex biomolecule containing magnesium. The molecule contains special ring shaped structures that capture preferred wavelengths of light. Green is not "captured" so it is reflected back to our eye.
I do know that plants may contain modified chlorophyll and
other pigments to take advantage of the type of light available
to them. One example are sea plants where only certain wavelengths of light may reach specific depths and the plants have evolved to capture this light for energy.
